Welcome to Symonym

Symonym is an advanced simulation software suite that includes a
packager, license management, and most importantly, a free,
cross-platform player that allows users to browse the repository of
public simulations. Simulations that are appropriate for the
performance level of the browsing machine can then be downloaded and
viewed.

Simulation of Brainstem GP 2.0 and Unicoder

In many cases, the user can then interact with the simulation via common
machine interfaces as though they were interacting with the real,
physical version of the controllers, robots, and sensors being
simulated.
